OWINGS MILLS, Md. — Returning to the practice field for the first time since their public workout at M&T Bank Stadium over the weekend, the Ravens were without safety Ed Reed during the opening portion of practice Monday afternoon.

Midway through Saturday’s practice, the veteran appeared to bang his left leg but finished the workout without any apparent concerns. Reed walked out to the field to watch the latter portion of practice while sporting a sleeve on his left leg. Reed received the day off last Monday along with linebacker Ray Lewis but has practiced every other day since reporting to training camp on July 25.

In addition to the laundry list of players missing at the start of practice, right guard Marshal Yanda, wide receiver Jacoby Jones, defensive end Pernell McPhee, and running back Anthony Allen did not finish Monday’s practice. Yanda left the field at the conclusion of the opening special teams period and showed no visible discomfort, but he never returned over the course of a practice that lasted over two hours.

“Jacoby, I pulled him out about midway through,” Harbaugh said. “I just felt like he’d done enough. Marshal, I pulled him out early in the practice and just felt like he’d had enough. And Pernell, I’m not sure about. That wasn’t me, so we’ll have to find out about that one.”

Wide receiver Tandon Doss (hamstring), cornerback Cary Williams, and tight end Ed Dickson returned to the practice field on Monday. Doss had been sidelined since the first week of camp while Williams missed workouts on Friday and Saturday but told reporters the absence wasn’t related to his surgically-repaired hip and he was simply resting. Dickson was poked in the eye during the stadium practice, but the third-year tight end told reporters he would be fine.

In addition to Reed, linebacker Dannell Ellerbe and defensive tackle Ma’ake Kemoeatu were new absences on Monday. However, each player missed one practice last week.

Upshaw has now missed seven straight practices and hasn’t worked since July 28 after suffering a sprained shoulder in a collision with Pierce. While the Ravens are eager to see him return to the practice field, Harbaugh reminded everyone there are plenty of reps remaining in the preseason and the team is not deviating from its plan to replace linebacker Terrell Suggs.

“He got lots of reps in the offseason program earlier,” Harbaugh said. “We just need to get him out there participating. Obviously, Sergio’s a big part of that. Albert’s gotten a lot of reps. Paul Kruger’s been out there the whole time. Courtney’s a piece that we need to evaluate and develop, and he’ll be in there soon enough.”

Suggs remains on the non-football injury list while wide receiver David Reed is on the physically unabe to perform list, and both are expected to miss the entire preseason.

The Ravens will practice again on Tuesday before traveling to Atlanta for their preseason opener on Thursday night.
